Of course most RTV sealers will lose mass, regardless of vacuum or normal pressure, because thinner is added to most Room-Temperature Vulcanisation sealers to make their application easier and provide better adhesion. Thinner will diffuse to the surface and evapourate with time, faster in vacuum or at high temperatures, as any volatile liquids do.
This mass loss will not anyhow harm RTV sealer at all. But it could contaminate vacuum in some sensitive equipment and even damage sensors or poison some ion trap or whatever inside vacuum chamber sealed with this sealer. For such purposes thiinnerless 2k RTV sealers manufactured. But they are harder to apply and more expensive. There is no any sense to use them for sealing large surfaces for space, because nobody cares about contaminating outer space with few grams of thinner molecules.
Funny, you already tried to push exactly same crap here earlier. Somebody decided that everybody forgot about it and it is time for next round of pushing narrative?
According to NASA's own documents, the RTV used to seal the windows of the spacecraft loses mass under only 10^-6 tor vacuum:
